I've been using the $30 APP called Cine Meter II by Adam Wilt.
Yeah...it's an iPhone app...but it frikkin' WORKS.
This is good to know... did you buy the luxi dome for it as well? I remember reading about this when it first appeared but had forgotten about it. For the price - it would be as much fun to goof with as it would to use on paying gigs, me thinks.
I have a Sekonic L-408 that is zippered in my camera bag. Can't remember the last time I actually used it on a shoot... so maybe I'd occasionally open the app while checking email on a shoot...
